Angiomyolipomas (AML) are generally known as benign tumors. The kidney is the most common location of this tumor, and the liver is reported as the second most common site. Occurrence in other tissues is extremely rare. For instance, some cases of AML originating from the nasal cavity have been previously reported. We describe an AML case arising from the nasal cavity of a 56-year-old man. The patient had been complaining of nasal obstruction and foreign body sensation in the nasopharynx and was initially treated with preoperative angio-embolization. AML was then totally removed by endoscopic surgery without complications. He has been asymptomatic and has had no evidence of recurrence for 2 months after surgery.

PURPOSE: To report the initial clinical outcomes of the newly devised sliding loop technique (SLT) used for renorrhaphy in patients who underwent robot-assisted laparoscopic partial nephrectomy (RALPN) for small renal mass. MATERIALS AND METHODS: We reviewed the surgical videos and medical charts of 31 patients who had undergone RALPN with the SLT renorrhaphy performed by two surgeons (CWJ and CK) between January 2014 and October 2014. SLT renorrhaphy was performed after tumor excision and renal parenchymal defect repair. Assessed outcomes included renorrhaphy time (RT), warm ischemic time, perioperative complications, and perioperative renal function change. RT was defined as interval from the end of bed suture to the renal artery declamping. RESULTS: In all patients, sliding loop renorrhaphy was successfully conducted without conversions to radical nephrectomy or open approaches. Mean renorrhaphy and warm ischemic time were 9.0 and 22.6 minutes, respectively. After completing renorrhaphy, there were no adverse events such as dehiscence of approximated renal parenchyma, renal parenchymal tearing, or significant bleeding. Furthermore, no postoperative complications or significant renal function decline were observed as of the last follow-up for all patients. The limitations of this study include the small volume case series, the retrospective nature of the study, and the heterogeneity of surgeons. CONCLUSIONS: From our initial clinical experience, SLT may be an efficient and safe renorrhaphy method in real clinical practice. Further large scale, prospective, long-term follow-up, and direct comparative studies with other techniques are required to confirm the clinical applicability of SLT.

PURPOSE: To acquire the useful diagnostic information through the analysis of the clinical and radiological characteristics of mandibular unicystic ameloblastoma. MATERIALS AND METHODS: The researchers compared and analysed the clinical and radiological features of 79 cases of mandibular unicystic ameloblastoma confirmed by histopathlogic examination. RESULTS: The results of our research showed that unicystic ameloblastomas occurred more frequently in males than in females and the incidence is the highest in the 2nd and 3rd decades. These lesions occurred most frequently in angle-ramus area, mandibular molar area, and anterior area in descending order respectively 68.4%, 24%, and 7.6%. These lesions had smooth (54.4%) rather than undulating (45.6%) borders. These lesions showed welldefined borders in 59.5% among all the cases. Root resorption and loss of lamina dura were observed as 55.7% and 58.5% respectively. Displacement of mandibular canal was observed in 55.9% among all the related cases. Internal pattern of lesional radiolucency was observed as even (49.4%) or uneven (50.6%). CONCLUSION: These results would be helpful in diagnosing of mandibular unicystic ameloblastoma.

Hyperthyroidism is a well known cause of atrial fibrillation. It is also known that control of hyperthyroidism can usually curb thyrotoxic atrial fibrillation and restore sinus rhythm. In this study, 282 patients with hyperthyroidism were investigated to quantify the incidence of atrial fibrillation, and to identify the vulnerable groups. In addition, we compared two groups of subjects with atrial fibrillation-one group with hyperthyroidism and the other group without

Glomus tumor, a rare benign vascular tumor arising from the neuromyoarterial apparatus, is usually located at the tip of digits, especially at subungual region. Most of this tumor present typical symptoms such as hypersensitivity to cold, severe pain and point tenderness but frequently misdiagnosed as neuroma, gout or causalgia. Concerning about the origin of the glomus tumor, there were few written reports about extra-digit vascular origin glomus tumor especially that occurred at forearm artery. Recently we experienced a glomus tumor which arised at forearm radial artery and reported with review of literatures. A 31-year-old female admitted to our department with pulsating, slow growing, tender mass at her left forearm for about 1 year. After diagnostic evaluation of ultrasonography and magnetic resonance angiography, surgical resection was performed under the diagnosis of radial artery aneurysm but the histologic final diagnosis made by special immunohistochemical stains was glomus tumor originated from radial artery. The postoperative course was uneventful up to 2 years of follow up.

Spontaneous renal subcapsular hematoma is a rare, life-threatening condition that is usually caused by benign and malignant renal tumors, vascular diseases, inflammatory disorders, blood dyscrasias, and seldom suspected clinically. The characteristic clinical features are abdominal pain, a mass in the flank and signs of internal bleeding. Severe preeclampsia is also a major contributing factor of the renal hematoma. Because renal function is decreased in spontaneous renal subcapsular hematoma, physicians should be aware of the clinical symptoms and signs, appropriate investigation and management may be life-saving. This case of spontaneous renal subcapsular hematoma and acute renal failure complicated by severe preeclampsia, which occurred after delivery and was treated conservatively.

PURPOSE: To determine the prevalence of severe distress and its correlates among Cheju medical college students. METHODS: Data were gathered in December 2005, and all medical college students were included. Of a total of 170 medical college students, 52(30.6%), 41(24.1%), 37(21.8%), and 40(23.5%) were 1st, 2nd, 3rd, and 4th year students, respectively. The questionnaire for sociodemographic information included age, sex, year, hometown, accommodation, education level of parents, socioeconomic status of parents, GPA(grade point average), and standing. Subjective sense of health status, level of health concern, smoking habit, drinking habit(CAGE), sleep pattern, degree of obesity, and body image satisfaction were included to reveal health habits and health behaviors of the subjects. CES-D for depression, Psychosocial Well-being Index(PWI) for stress level, State-Trait Anxiety Inventory(STAI) for level of anxiety, and SCL-90-R(Symptom Checklist 90 revised) for level of general psychopathology were used RESULTS: 1st year students were 4.338 times(95% CI; 1.412-13.324) more likely than other years to experience severe distress. Students who felt that they had insufficient time for relaxation showed 5.027 times(95% CI; 1.489-16.969) higher prevalence of severe distress than those who felt they had sufficient time for relaxation. Those with poor self-esteem were 18.347 times(95% CI; 5.484-61.382) more likely to experience severe distress than those with 'good' self-esteem. CONCLUSION: Offering various programs for improving coping skills, advanced counseling program, or tutoring system and providing sufficient relaxation timeby various methods, such as modifying curriculum, are needed to ameliorate severe distress.

PURPOSE: To investigate changes in nocturia and predictive factors for improvement after photoselective vaporization of the prostate (PVP) for patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A total of 103 patients who complained of nocturia of > or =2 times per night on baseline frequency-volume chart (FVC) and who underwent PVP were included in this retrospective study. All patients underwent a preoperative evaluation for BPH including multichannel video urodynamics. The efficacy of the PVP was evaluated at 1, 3, 6, and 12 months postoperatively by use of the International Prostate Symptom Score (IPSS) and FVC. Subjective and objective improvement of nocturia were defined as a reduction of > or =50% in nocturnal frequency compared with baseline on the IPSS and FVC, respectively. RESULTS: As shown by the IPSS and FVC, nocturia was significantly reduced starting from 1 month after PVP. The percentage of patients with improvement in nocturia was 20.0%, 20.7%, 36.2%, and 27.9% on the IPSS, and 30.1%, 48.6%, 52.2%, and 54.5% on the FVC at 1, 3, 6, and 12 months after PVP, respectively. None of the baseline parameters, including the presence or absence of nocturnal polyuria (NPU), reduced nocturnal bladder capacity (NBC), and detrusor overactivity (DO), were associated with improvement of nocturia. CONCLUSIONS: Nocturnal frequency was significantly reduced from the early postoperative period after PVP. Improvement in nocturia after PVP was not affected by baseline nocturnal frequency, the presence or absence of preoperative NPU, or reduced NBC or DO on baseline urodynamics.

Aortic valve replacement with aortic allograft has been considered a treatment of choice for aortic valve disease secondary to bacterial endocarditis because of its good hemodynamic performance and higher resistance to infection. The aortic root replacement technique might be superior to the subcoronary allograft implantation technique with regard to aortic regurgitation. A 46 years old male patient had acute aortic regurgitation with progressing heart failure secondary to acute bacterial endocarditis. The patient underwent emergent aortic root replacement using 20 mm aortic allograft. At operation, right coronary cusp perforation and heavy calcification of commissure between right and left coronary cusp were observed. The patient recovered well and postoperative echocardiography demonstrated no aortic regurgitation. Inflammatory signs were subsided after 8 weeks of antibiotics therapy. Medically uncontrolled acute bacterial endocarditis was treated successfully by aortic root replacement using aortic homograft.
